- the reference numerals 56, 57 designate switches which are adapted to be switched ON and OFF by the sector gear 81 thereby to change over the rotation of the driving pulley 86 of the motor 85 in normal and reverse directions.
- the player body 2 of the disk player 1 is formed at its front side surface with a rectangular opening 3, in which a front side surface (right side surface) 20a of the disk tray 20 is exposed at the lower side of the opening 3, while a lid 4 covering the front end side is openably installed at the upper side of the opening 3.
- the motor 85 for the mechanical chassis upwardly and downwardly driving purpose is driven, so that the front side of the mechanical chassis 50 ascends and therefore the turntable 70 and the optical pickup 75 ascend.
- This ascending of the turntable 70 and the like causes the disk 100 to be mounted on the upper surface of the turntable 70 and to ascend over the front opening 30a of the sub-chassis 30 through the opening 22 of the disk tray 20.
- the ascended disk 100 is rotatably clamped between the turntable 70 and the chucking member 41 of the cartridge carrier 40 as shown in FIG. 8, so that the playback is made under the action of the optical pickup 75. Ejection of the single body of this disk 100 is carried out under the returning slide-movement (unloading action) of the disk tray 20 which movement is reverse in action to the loading action of the disk tray 20.
- the cartridge 110 is inserted to the front side of the cartridge carrier 40 upon pushing the lid 4 of the player body 2 with the tip end of the cartridge 110. Then, the tip ends 42a, 42a of the nails 42, 42 of the cartridge carrier 40 are respectively brought into engagement with the engaging grooves 111, 111 at the opposite sides of the cartridge 110, so that the cartridge 110 is grasped, as shown in FIGS. 1 and 9.
- the switch 48 is operated to drive the motor 37 for the cartridge carrier driving purpose.
- the roller 62 of the shutter opening-closing lever 60 rotatably supported through the support shaft 61 on the main chassis 10 is brought into contact with the tapered surface 47 formed at the left side bottom wall section 40c of the cartridge carrier 40 in the course of the loading of the cartridge 110, so that the shutter opening-closing lever 60 gradually rotates counterclockwise as seen from FIGS. 9 and 10.
- This counterclockwise rotation of the shutter opening-closing lever 60 causes the pin 63 at the tip end thereof to push the left side upper end edge of the shutter 113 of the cartridge 110 so that the shutter 113 starts to gradually open as shown in FIG. 10.
- the shutter 113 of the cartridge 110 is fully opened while the rear end face of the cartridge carrier 40 is brought into contact with the switch 49A as shown in FIG. 11. This causes the motor 37 to stop, in which the disk encased in the cartridge 110 is located above the turntable 70, completing the loading of the cartridge 110.
- the motor 85 for the purpose of upwardly and downwardly driving the mechanical chassis is rotated, so that the front side of the mechanical chassis 50 ascends and therefore the turntable 70 and the optical pickup 75 ascend.
- This ascending of the turntable 70 and the like causes the disk 101 within the cartridge 110 to be mounted on the upper surface of the turntable 70 and to ascend.
- the ascended disk 101 is rotatably clamped between the turntable 70 and the chucking member 114 inside cartridge 110 as shown in FIG. 7, so that the playback is made under the action of the optical pickup 75.
- Ejection of the cartridge 110 is carried out under the returning slide-movement (unloading action) of the cartridge carrier 40 which movement is reverse in action to the loading action of the disk tray 20.
- both the single body of the disk 100 and the disk 101 encased in the cartridge 110 can be respectively played back. Accordingly, it becomes unnecessary to use two disk players for the only playback purpose, and therefore cost for playback becomes low.
- conventional troublesome operations for encasing the disk in and taking out the disk from the cartridge have become unnecessary when playback or the like of the disks is made, so that the both disks 100, 101 can be played back respectively by simple operations. In this connection, it would be convenient to encase only a frequently used disk in the cartridge to be used.
- the disk tray 20 for loading the single body of the disk 100 to a predetermined position inside the player body 2 and the cartridge carrier 40 for loading the cartridge 110 storing the disk 101 to a predetermined position inside the player body 2 are arranged to form a two-stage in a vertical direction through the respective chassis 10, 30. Accordingly, the player body 2 is arranged small-sized without increasing its length. Additionally, both the disks 100, 101 can be respectively played back with only one disk player 1. These save a space as an installation place for the disk player 1.
- the cartridge carrier 40 for loading the disk 101 to the predetermined location in the player body 2 serves also to clamp the single body of the disk 100 in cooperation with the chucking member 41 during the playback of the single body of the disk 100. This renders unnecessary, for example, a mechanism and the like for pushing up upwardly the chucking member adapted to clamp the single body of the disk, thereby enabling a mechanism for loading the single body of the disk 100 and the cartridge 110 to be simplified. As a result, the player body 2 can be small-sized while enabling the disk player 1 to be offered at a low cost.
- the rotational movement of the shutter opening-closing lever 60 for opening and closing the shutter 113 of the cartridge 110 encased therein the disk 101 is in operative relation to the loading and unloading actions of the cartridge carrier, and therefore it is unnecessary to use a driving source such as a motor for driving the shutter opening-closing lever 60. This reduces the number of component parts thereby enabling the whole disk player 1 to be lowered in cost and small-sized with a weight-lightening.
- the disk player or recorder includes the disk tray for loading the single body of the disk to the predetermined position in the player body.
- the cartridge carrier is provided to load the cartridge to the predetermined position in the player body.
- the turntable is provided such that either one of the disks loaded at the predetermined position in player body is mounted thereon.
- the optical pickup is provided to make the recording operation and/or the playback for either one of the above-mentioned disks loaded at the predetermined position in the above-mentioned player body. Accordingly, the recording operation and playback can be effectively carried out for both the single body of the disk and the disk encased in the cartridge with only one player, so that two disk players respectively exclusively used for the two kinds of disks are unnecessary to be provided as conventional.
- the recording operation and playback for the two kinds of the disks can be accomplished at low cost while saving a space for installation of the disk player.
- the above-mentioned two kinds of disks can undergo their recording operation and playback with a simple operation.
- the shutter of the cartridge is adapted to be openable and closable in operative relation to the loading and unloading actions of the cartridge carrier, and therefore no separate driving source is necessary so that the number of component parts is reduced. As a result, the whole disk player can be further lowered in cost and small-sized.
- the cartridge carrier is provided with the chucking member for chucking the single body of the disk at the recording operation and playback, the cartridge carrier functions not only to carry the disk but also to chuck the disk. Accordingly, mechanisms such as that for loading the single body of the disk and the cartridge can be simplified in structure, so that the whole disk player can be further more lowered in production cost and small-sized.
